India’s Power Sector:

1. At a Glance

• India's electricity supply ecosystem spans generation, transmission and distribution across Union + State jurisdiction (Concurrent List, Entry 38) governed primarily by the Electricity Act, 2003 [1][3].
• Installed capacity has crossed 520.51 GW (Jan 2026) with non-fossil share at 52.3%, making India the 3rd-largest renewable energy producer globally [2][6].
• Aspirants must master schemes (Saubhagya, DDUGJY, RDSS, PM-Surya Ghar, PM-KUSUM), tariff/discom reforms (LPS Rules 2022), and the energy-transition target of 500 GW non-fossil by 2030.

2. Why in the News

• PM Surya Ghar: Muft Bijli Yojana crossed 9,566.89 MW rooftop solar by 20 Mar 2026 [2].

3. Background & Evolution

5. Multi-Dimensional Analysis

Economic

• Cross-subsidy distortion: industrial tariffs subsidise agriculture/domestic — Bill 2025 seeks rationalisation to lower manufacturing costs [3].
• LPS Rules 2022 cut genco legacy dues from ₹1,39,947 cr (Jun 2022) to ₹49,451 cr (Jan 2024) → improved sectoral liquidity [6].

Social / Equity

• Saubhagya delivered universal household electrification — 2.86 cr connections, mostly BPL [1].
• PM Surya Ghar promises 300 free units/month to 1 crore households via rooftop solar [2].

Environmental

• Non-fossil share crossed 50% in 2025, supporting NDC update of 50% non-fossil installed capacity by 2030 [2][7].
• 2025 saw highest-ever RE capacity addition; solar 34,955 MW + wind 4,613 MW in FY26 YTD [2].

Federal / Administrative

• Electricity is Concurrent; tariff-setting by SERCs; political reluctance to raise farm tariffs limits discom viability.
• States accessing extra borrowing space (0.5% of GSDP) conditional on power-sector reforms [8].

Technological

• Smart metering (prepaid, AMI) under RDSS — 4.05 crore deployed; enables ToD tariffs, loss reduction [2].
• Green Hydrogen Mission, BESS (Battery Energy Storage Systems) PLI, ISTS waivers driving grid integration.

8. Mains Relevance

• GS-II: Government policies — federal centre-state issues on electricity (Concurrent List).
• GS-III: Infrastructure (energy); Environment — energy transition; Inclusive growth.
• Plausible stems: 1. "Discuss how the Revamped Distribution Sector Scheme addresses the structural weaknesses of India's DISCOMs. Are the reforms adequate?" 2. "India's commitment of 500 GW non-fossil capacity by 2030 requires deep distribution-side reforms. Examine." 3. "Cross-subsidisation in electricity tariffs has run its course. Critically analyse the proposed Electricity (Amendment) Bill, 2025."

10. Common Errors / Trap Areas

• Saubhagya ≠ DDUGJY: Saubhagya = household connections; DDUGJY = village/feeder infrastructure [4].
• PM Surya Ghar (Feb 2024) is rooftop solar (MNRE); do not confuse with PM-KUSUM (solar pumps, also MNRE) [2].
• Electricity is Concurrent (Entry 38), NOT State List.
• RDSS outlay is ₹3.03 lakh crore total, not the central GBS (which is ₹97,631 crore) [5].
• CERC regulates inter-state, NOT intra-state tariffs (SERCs handle the latter).
• India is 3rd in renewable installed capacity globally, not 2nd [7].
